Setting Web project properties

There are many Web project properties that you can set that affect the phases in the lifecycle of your project and its dependencies on other Web resources and Web development processes. You might want to verify or update these properties after you have updated an existing project or have imported Web resources into a project .

To view or set Web project properties, do the following:

  1. Right-click on a Web Project, and from the pop-up menu select Properties .
  2. Select a property type in the left pane of the Properties dialog to view or update properties in the Web project. For each property, you can apply changes and modify default settings. Based on whether you have a static or a dynamic Web project, the following property types are available:
    Provides general information about project type, location, and modification status.
    BeanInfo Path (Dynamic Web project only)
    If you select the Enable Beaninfo Introspection on this project, you can specify the contents and order of Java™ Bean search paths to provide Bean information relevant to the project. You can add, remove, and reorder (using the Up and Down buttons) the packages used to include Bean information.
    Add, remove, or reorder external tools in the build order. When you select New to create a new external tool to the list, the New External Tool wizard opens, so that you can define the new build tool.
    Java EE (Dynamic Web project only)
    Identify Web level specification and modify context root and Web content folder name
    Java Build Path (Dynamic Web project only)
    View or change the information about the Java build path that you supplied when creating the project using the Create a DynamicWeb Project wizard. Whenever the Web project is rebuilt, any class files that are created or updated will be output to the specified output folder.
    Note: A library entry on the Java build path will remain there unless the actual JAR file is deleted from the WEB-INF/lib folder. If you remove a library path entry but not the JAR file, the library entry will be re-added to the path automatically.
    Java Compiler (Dynamic Web project only)
    Define whether to use workspace settings or project setting for compiling Java code, including settings for Problems, Style, Compliance and Classfiles, and Build Path.
    Javadoc Location (Dynamic Web project only)
    Define a default location (URL) for any Javadoc available to the project.
    Java JAR Dependencies (Dynamic Web project only)
    Define and reorder JAR dependencies for the project. Note that these dependencies may differ based on a Web project's association with multiple Enterprise application projects.
    JSP Task Tags
    Add, edit, or remove JSP task tags and assign tag priorities. These "to do" items appear in your Tasks view.
    JSP Compilation
    Specify when in the build process a JSP should be set to compile
    JSP Fragment (dynamic Web project only)
    Define default encoding, page directive, and content type values for JSP fragment documents in the web project.
    Links Validation/Refactoring
    Define project-level link management and validation settings. These settings override corresponding settings in the Workbench Preference settings for the current project.
    Project References
    Reference other Web projects that exist on your workbench workspace.
    Select the server instance used to perform necessary development, test, and publishing functions for the project.
    Specify which validators should run for the project, and whether validation should occur automatically when resource updates are written to the project. The available validators are based on the types of resources in your project. By default, validators are automatically run when you save resources in a Web project. If you do not want validators to run automatically when you save these resources, enable the Override validation preferences option and disable the Run validation automatically when you save changes to resources option.
    Note: You can also disable automatic validation (and builds) for all projects by disabling Perform build automatically on resource modification from the Workbench properties. If you disable automatic builds, you can manually run a build (and validation) by selecting Project > Rebuild project .
    Web Content Settings
    Provide any applicable Web content settings for a Web project. You can specify the document type, CSS profile, and target device.
    Web Project Features
    Select the features you want to be enabled for your Web project, such as Page Template support.
  3. When you have completed updates to Web project settings, click OK to save and close the Properties dialog.
